ICE-FORMER DEVICE.

To allwho'm it may concern:

Be it known that I, Trmooonn SwANso a citizen "of the United States, residing at Lynn Center,"in the county of Henry and State of' lllinois, have invented a new and Improved Ice-Former Device, of which the following is a specification.

My invention is" in the nature of a mold or form for domestic purposes by the use of which natural ice is frozen in blocks or cakes 1 for refrigerators and my said invention primarily has for its purpose the production of an ice mold orforming device of an exceedingly inexpensive and simple construction,

thatcan be readily applied for useby any one and by whichsolid form ice cakes are quickly prod'uced,-as desired.

Another object of my invention is to pro 'vi'd enn'ice forming device in which the parts are of such arrangement that danger of'thejice cake bulging or cracking,v as it freezes'solid, is prevented, and theseveral parts that constitute the form may be readily spread'to providefor quickly and convenlently removing the solid ice cake or block therefrom;

*Withbthen objects in View that will be hereinafterexplained, my invention is a de: vice forjthe purpose stated that'embodies the peculiar features of construction and combination of'parts outlined in the following descriptiomspecifically pointed out in the appended claim and illustrated in the accompanying drawings, in which:

Figure 1 is 'aperspective view that illustrates my ice forming device as in practical use.

Fig.2 is a vertical section of the same and shows the manner in which the bottom 010- i partsv that constitute my ice forming device are arranged for shipping.

My ice cake forming device, which is particularly adapted for use in cold weather for forming ice cakes for refrigerators consists of a bottom piece or blank 1 whose corner ed es are slit as at 10 and preferably formec of stifl' sheet metal (galvanized Specification of Letters Patent. Patented July 29, 1919. Application filed January 18,1918. Serial No. 212,436.

iron) and a body portion 2 formed up from a single sheet of'galvanized iron.

In shaping up the parts 1 and 2, the edges 11 of the said bottom 1 are bent up about one-half an inch to form a trough-like member, as is clearly shown in the drawings.

The body sheet 2 is bent to form the four sides or members 20--2O and the ends of the said body piece 2 are bent out at right angles to form vertical flanges 2121 and, when shaping up the device, the said flanges 21 are clamped fluid tight between two wooden blocks or strips 3-3 that are provided with apertures 30-30 to receive the clamp bolts 4- 1 that also )ass through edge notches 5--5 in the body fianges21-21 and are secured for clampin the said parts together by nuts 6-6, as s iown.

The body sheet 2, when bent to form the four sides 20, has the horizontal shapeof the troughdike bottom 1, but the said body that is formed by bending up the sheet 2, is sufficiently smaller than the bottom 1, whereby, when it is set in place of the troughlike bottom 1, a water receiving space surrounds the bottom edge of the form or body composed of the sides 20, as is clearly shown in Figs. 1 and 2,- by reference to which it will be also observed the bottom edge of the vertical flanges 21 are notched, as at 22, which notches register with like notches 33 on the lower ends of the two wooden clamping strips 3-3.

By forming the lower ends of the flanges properly positioned with its four sides spaced from the coincident flanged portions 11-11 of the trough-like bottom 1.

In using the device, the body 2 is set into the body 1. Water is then poured into the trough-like bottom sufiicient to close the joint between the body and the said bottom, which, when frozen, makes a water tight joint for the bottom of the mold or former.

The former or mold is then filled with Water, preferably ice cold water, since if water taken from the well is used, it will melt the ice seal at the bottom. The quick est results are had by having a tank with ice cold water at hand when filling the form or mold.

To prevent the ice block or cake as it freezes solid within the form or mold 2 from bulging or cracking, I use a core 7 of some element that maintains a temperature 21 and the strips 33 with the notches 22 and 32, as stated, the form or body is held' above-freezing and which is supported within the mold or form;

' In practice I have found that a bottle filled with kerosene oil forms a simple, in expensive and easily provided core member. When setting up the device for use, to get the best results it should be mountedrupo'n 1 a base composed of 2 bye side timbers joined by cross slats, since by supporting the ice forming devicethereon, ample space is provided for the. circulation of cold air under the bottom and sides of-the device and, further'by providing a basesupport, as stated, several ofthe ice forming devices may be supported upon the one base.

The core? is hung to project down into the form 2, in such manner that it is free i '-of the bottle up and thereby gives more room for water left in the center of the cake. to freeze, it being understood thatthe V tendency of the lateral expansion of theice cake is taken care of by the constant filling up ofthe space left underfthe core as it beingpushed up by the solid ice cake. that continuously forms under the bottleor core, After the water is frozen into a solid cake, as stated, the said cake is readily removed by loosening up the, nuts and clamp. bolts and removing the wvood en strips. 8. The edges of the body at one side can then be sufficiently spread to allow for pulling the mold or form from the icecake. Should the sides of the form tend to stick to the cake, they can be easily loosened With a thin table knife. 7

Copies of this patent may bebbtained fer device is especially useful in places where artificial ice is not to be had. It is understoodthat in marketing my 111- vention, only the bottom 1, the body 2, the V nutted clamp bolts and strips and the core support are assembled, since the core member can be readily supplied by the-user. 7 My device is as a new article in which the parts 1 and 2 may be packed flatwise with the nutted clamp bolts the clamp strips, see Fig. 5, it beinglmdor iwod the mpl tk d o nstruct ons accompany? 2; the Sa P rt W l enab e theuser o quickly tion. 7 I 1 a What I claim is:
